IT Engineer, Internal AI Infrastructure

What you'll do at Figma:

• Design and build the hosting golden path for internal AI applications, bots, and agents, including runtime patterns for long-running workflows, scheduled jobs, and agent execution
• Build the model routing layer that directs tasks across frontier and lower-cost models based on cost, capability, and policy with a full audit trail
• Stand up observability, usage analytics, audit logging, and per-team cost attribution for AI workloads across the company
• Integrate identity, access, and security patterns (Okta-connected by default) so every internal AI app is safe on day one, including the sanctioned path for workflows touching customer, financial, or people data
• Partner with engineers on our product AI infrastructure teams to share gateways and telemetry rather than building parallel systems
• Help shape the team's platform strategy, roadmap, and engineering best practices as a founding member of the infrastructure pillar

We'd love to hear from you if you have:

• 5+ years of software engineering experience, with significant time in infrastructure, platform, or backend engineering
• A track record of building internal platforms or paved paths that other engineers and teams adopted, not just maintained, with excellent communication skills collaborating across security, IT, and business teams
• Strong system design skills and experience architecting resilient, observable production systems
• Hands-on experience with LLM operations: model gateways or routing, agent runtimes, evals, or cost/usage instrumentation
• Experience with identity and access management in an enterprise environment (e.g., Okta, SSO, secure service-to-service auth)

While it's not required, it's an added plus if you also have:

• Experience building internal AI platforms or workspaces (the Ramp Glass / JPMorgan LLM Suite category) or developer platforms at a comparable scale
• Familiarity with MCP, agent orchestration frameworks, or skill/plugin registry patterns
• Experience working within audit and compliance programs (SOX/ITGC) or building systems with audit requirements
• A history of being the first infrastructure hire on a small team, comfortable setting standards from scratch across a broad scope of responsibilities
